AN/SYQ-7A(V) Naval Modular Automated Communications System

The Naval Modular Automated Communications System (NAVMACS) Model II AN/SYQ-7A(V), commonly referred to as NAVMACS II, is a ship-to-ship or ship/shore/ship message processing system. NAVMACS processes and records all incoming and outgoing message traffic and serves as an automated shipboard terminal for the Common User Digital Information Exchange System (CUDIXS). The NAVMACS system guards up to four Broadcast channels and automatically processes and prints a hard copy of any high precedence message requiring immediate response. The NAVMACS system architecture provides an RS-232 serial output capability for interfacing with other Local Area Networks (LANs), enabling NAVMACS message traffic to be distributed to and received from terminals/workstations in various spaces throughout the ship. The NAVMACS sends and receives messages via the Fleet Satellite Communications (FLTSATCOM) system at 9600 kbs, or the High Frequency (HF) system at 9600 kbs Independent Side Band (ISB), 1200 kbs High Speed Fleet Broadcast (HSFB), or 2400 kbs HF digital links.
